Oscar®-winning actress Charlize Theron appears to be one lucky gal at the height of her career. But for Charlize, there's no such thing as luck. "Luck doesn't exist in my vocabulary anymore," says Charlize. "It's a bad habit. I said it the other day. Ironically, somebody said the same thing to me the other day, 'Don't say luck.' So I'm stopping myself."

Instead, Charlize agrees with Oprah's take on success. "There's no such thing as luck," Oprah tells Charlize. "There's only preparation meeting the moment of opportunity. ... If you weren't prepared when the opportunity showed up, nothing would have happened."
